Abstract :
A data acquisition system permitting turn-by-turn orbit measurements has been employed at CESR to study the optics for the injected electron beam. An optimization algorithm uses these measurements to determine the effective lattice functions describing the behavior of the injected electrons. We present the application of these measurements to calculations of injection acceptance envelopes, which include parasitic beam-beam interactions with the stored positron beam.
